What I'm looking for

I'm looking to build AI-assisted, high-traffic production systems with remote international teams, using React, Next.js, TypeScript, Go, and event-driven architecture.

At Fanatics, I rebuilt a manual raffle workflow into an automated Go, Kafka, and Temporal pipeline that more than doubled weekly product drops to 8–10. I also delivered backend foundations for international expansion, improved endpoint response times by up to 90%, and resolved Kafka environment isolation issues before launch.

I've shipped A/B-tested financial experiences at Coinbase, including a payment optimization that lifted conversion 15% and revenue 8% in a key market. Across crypto, e-commerce, gaming, and agency work, I build production systems with React, Next.js, TypeScript, GraphQL, and Go—and I'm now applying Claude Code and spec-driven development to AI-assisted production workflows.
